More quotes by Carl Sagan
By looking far out into space we are also looking far back into time, back toward the horizon of the universe, back toward the epoch of the Big Bang.
Carl Sagan
Books are key to understanding the world and participating in a democratic society.
Carl Sagan
There is much that science doesn't understand, many mysteries still to be resolved. In a Universe tens of billions of light-years across and some ten or fifteen billion years old, this may be the case forever. We are constantly stumbling on new surprises
Carl Sagan
Imagination will often carry us to worlds that never were. But without it we go nowhere.
Carl Sagan
Every time you look up at the sky, every one of those points of light is a reminder that fusion power is extractable from hydrogen and other light elements, and it is an everyday reality throughout the Milky Way Galaxy.
Carl Sagan
The Apollo pictures of the whole Earth conveyed to multitudes something well known to astronomers: On the scale of the worlds - to say nothing of stars or galaxies - humans are inconsequential, a thin film of life on an obscure and solitary lump of rock and metal
Carl Sagan
There is a report that says that kids who watch violent TV programs tend to be more violent when they grow up. But did the TV cause the violence, or do violent children preferentially enjoy watching violent programs?
Carl Sagan
I also wish that the Pledge of Allegiance were directed at the Constitution and the Bill of Rights, as it is when the President takes his oath of office, rather than to the flag and the nation
Carl Sagan
We humans appear on the cosmic calendar so recently that our recorded history occupies only the last few seconds of the last minute of December 31st.
Carl Sagan
It seems madness to say, 'We're worried that they're going to become addicted to marijuana' -- there's no evidence whatever that it's an addictive drug, but even if it were, these people are dying, what are we saving them from?
Carl Sagan
It is the responsibility of scientists never to suppress knowledge, no matter how awkward that knowledge is, no matter how it may bother those in power we are not smart enough to decide which pieces of knowledge are permissible, and which are not.
Carl Sagan
Observation: I can't see a thing. Conclusion: Dinosaurs.
Carl Sagan
The idea that God is an oversized white male with a flowing beard, who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by 'God,' one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity.
Carl Sagan
Science is an attempt, largely successful, to understand the world, to get a grip on things, to get hold of ourselves, to steer a safe course. Microbiology and meteorology now explain what only a few centuries ago was considered sufficient cause to burn women to death.
Carl Sagan
We've arranged a civilization in which most crucial elements profoundly depend on science and technology.
Carl Sagan
Across the sea of space, the stars are other suns.
Carl Sagan
It is the tension between creativity and skepticism that has produced the stunning and unexpected findings of science.
Carl Sagan
A celibate clergy is an especially good idea, because it tends to suppress any hereditary propensity toward fanaticism.
Carl Sagan
A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet.
Carl Sagan
If we can't think for ourselves, if we're unwilling to question authority, then we're just putty in the hands of those in power.
Carl Sagan
